Discord is completely back to normal.

The root cause was operator action. We were investigating some anomalous behavior on one of our systems (in our Guilds service) and we force-killed a process which unfortunately had a cascading impact. The system self-recovered like it was designed to, but that process took about 5 minutes for everything to settle down and return to normal.

Service is coming back to normal, we are monitoring.

We are online and investigating issues with Discord, affecting normal usage and sending messages.
